For this project, I implemented the genetic algorithm-based jigsaw puzzle solver described in “A Genetic Algorithm-Based Solver for Very Large Jigsaw Puzzles” by Sholomon et al [1]. This method involves producing a “child” solution from two “parent” solutions by detecting, extracting, and combining correctly assembled puzzle pieces. The solver developed by the paper’s team is able to accurately...

This project involved the use of two small, closely matched non-majors introductory biology classes to test the use of the Jigsaw method of teaching vs. a passive, instructor-oriented model of teaching. In this study, the Jigsaw method was used as a jumping off point for the teaching-learning of the material. Students were to learn the concepts of the chapters through the Jigsaw method and thei...

This paper proposes an algorithm for solving subsets of typical (canonical) jigsaw puzzles. This algorithm combines shape and image matching with a cyclic ‘‘growth’’ process that tries to place pieces in their correct positions. First, the jigsaw pieces are extracted from the input image. Then, the corner points of the jigsaw pieces are detected. Next, piece classification and recognition are p...

Abstract The structural and electrostatic properties of the single-walled two representative (8, 0) zigzag and (4, 4) armchair models of pristine and GaAs-doped on boron phosphide nanotubes (BPNTs) was investigated by calculating the nuclear magnetic resonance tensors and with performing the density function theory. The geometrical structures of all representative pristine and GaAs-doped mode...

This article presents an evaluation plan for Jigsaw– an interactive visualization system to support investigative analysis. Jigsaw provides multiple views of a document collection and the individual entities within those documents, with a particular focus on exposing connections between entities. We describe how we plan to evaluate Jigsaw on different levels: general usability first, then focus...

This paper presents an innovative description of the Jigsaw collaboration method within the context of open source e-learning ‘Learning Design’-based systems such as LAMS, with special reference to the learning of essential issues in Computer Science. These issues include: (a) the wide range of computer technology used in daily life and the consequences of such utilization, (b) the variety of c...
